Notes: LPAR & Power4 packaging

With the new Power4 processor technology on iSeries, dual processor chips and Multi Chip Module (MCM) are introduced. The picture shows 4 MCMs with each 4 chips, so we have a 32 way here. Every single processor that is activated via Capacity Upgrade on Demand will be seen by LPAR accordingly.

The detailed Hardware and Performance presentations have more information on i890 Power4 hardware architecture and implementation.

Notes: OS/400 Release Support

This foils shows the supported OS/400 releases on the different processor technologies. Note that V5R2 is required in all partitions on the i890 and that V4R5 is not supported on new i830 (#0153, #2349) and i840 (#0158, #0159) servers. Especially for models with SStar processors, remember that V4R5 partitions do not support I/O hardware that requires V5R1 or V5R2.

Notes: Virtual Ethernet Communication

1Gb Connections with no LAN Adapters/SwitchesV5R1 supports Virtual LAN - emulating 16 Mbps token ring LAN. Virtual Ethernet Communication is introduced with LPAR or between the integrated Windows server and the system. Each Virtual Ethernet LAN configuration is essentially 1Gbps connections with no LAN Adapters/Switches. With V5R2 virtual ethernet is enhanced to support up to 5 connections per (IXS / IXA ) integrated Windows servers. One of these 5 connections is automatically configured for Point to Point Communications with OS/400. This allows for Windows to Windows to OS/400 to Linux and so forth communication scenarios.

Performance ImprovementsThere are with V5R2 several changes made to the integration code to save Windows servers and the Virtual LAN that result in better performance for the following areas.

Windows Application to OS/400 ApplicationWindows to Windows CommunicationWindows File Level Back Up to OS/400 TapeFile level backup can now be done over virtual LAN rather then over the older 16Mbps Token-Ring internal LAN. Several test scenarios showed huge time improvements. The changes to backup application (not virtual LAN support) will be PTF-ed back into V5R1. One test that was done is described here after, although it is a preliminary test and certainly no benchmark, is intended to give you some idea of the improvements:The test data used was a storage space with many subdirectories each having thousands of objects some small, some big, and many subdirectories. The total was approximately 360 MB in size. For the testing we saved data to a save file and we saved directly to a 3580 Ultrium tape drive. All of these scenarios showed huge time improvements compared to older code. Saving one of the directories (approximately 360 MB) using the old code took 10 minutes 6 seconds. Saving the exact same data using the new code took 1 minute 25 seconds. The performance improvements for the save code will be PTFed back into V5R1. (Not Virtual LAN for integrated Windows servers)The series of PTFs for V5R1 that need to be applied to get the full benefit of these performance enhancements:

For 5722-SS1 the SI04511, for 5722-WSV the SI04503 and for WSV as a windows service pack the SI04504

Support Virtual Ethernet Communication is supported on the iSeries 270 and 8xx for the integrated Windows servers to communicate via Virtual Ethernet Communication the IXS or IXA owning partition should be on OS/400 V5R2.

Dynamic Processor Movement for LinuxWe can only do dynamic allocation of virtual processor units. We cannot change the amount of memory that Linux has dynamically. The memory of a Linux partition can be changed, but that would require the Linux partition to be restarted. The dynamic movement of processor capacity can be done with dedicated processors or processor units. Either way, the primary partition has to be at V5R2 to utilize this function.

Memory movement between "guest partitions" is not supported in V5R2.

Up to 10 Linux partitions per processorV5R2 now supports up to 4 OS/400 partitions per processor with a total of up to 10 partitions per processor. That is, a single processors can support up to 10 Linux partitions. You can use combinations of OS/400 and Linux partitions per processors. 10 times the number of processors, minus the number of OS/400 partitions, equal the number of Linux partitions allowed. (Maximum of 32 partitions on a system)

Notes: New views to move Memory and Processing power

These windows show the V5R2 options for moving memory or processing power from one partition to another partition.

Note the ability to schedule the movement. The scheduling support was added to V5R1 via a PTF after V5R1 general availability.

Notes: Miscellaneous LPAR enhancementsAs long as the primary is running V5R2, the minimum required interactive allocation for all secondary partitions is 0%.Secondary partitions running V5R1 (or any earlier releases that are allowed with a V5R2 primary) don't know about the 0% minimum, so if they see that other partitions are below the old minimum, they may attempt to donate some of their interactive capacity to the partitions which they perceive as having below-minimum allocations. This donation mechanism is just a redundant backup in case LPAR fails to enforce the old minimum allocation, it is not documented and has no external indication.

Example840 12-way with 10,000 CPWs in total of which 120 is interactive CPW.Primary partition = V5R2, and can have all 120 or some interactive CPW assignedSecondary partition 1= V5R1 and can have 0 interactive CPW assignedSecondary partition 2= V5R2 and can have 100 interactive CPW assigned.

Redundant donation mechanismIf you swapped the secondary interactive allocations, the V5R1 secondary with 100 CPW interactive would try to donate some interactive capacity to the V5R2 0 CPW secondary. The V5R2 secondary would be satisfied with 0 interactive, and would ignore the donation. In this case, the donated capacity would go unused. If both secondaries were running V5R1, then the below-minimum secondary would use the donated capacity.The only ways to prevent a V5R1 secondary from donating interactive capacity are to either

keep the interactive allocation to the V5R1 partition at or below the old minimum (so it has no excess to donate)or keep the interactive allocation of all partitions at or above the old minimum.

Information Center has links to additional information that enables you to:Use the LPAR Validation Tool (LVT) to help you design a partitioned system. The LVT provides you with a validation report that reflects your system requirements while not exceeding logical partition recommendations. Find SRC codes. The Logical partition SRC finder will find information about system reference codes (SRCs) related to logical partitions. This finder replaces the logical partition troubleshooting advisor. Learn how to Schedule logical partition resource moves. You can use the schedule function to move memory, processors, interactive performance, and I/O processors. Use the graphical wizard in iSeries Navigator to configure a guest partition.

LPAR Summary and Statement of DirectionIBM plans to further extend its self-managing systems initiative with self-optimizing and configuring capabilities that include native support for AIX in logical partitions alongside OS/400 partitions on IBM's eServer iSeries product line.

This would allow customers to leverage a broader range of application environments including OS/400, Windows, Linux, and now AIX on a single eServer. With this capability, a common set of resources can be managed and shared across a total customer solution, made up of applications targeted to different operating environments.This would extend the self-optimization capabilities of iSeries to meet the needs of customers in a simple, low cost, and efficient manner.

Virtual I/O and virtual ethernet support are part of these plans.

All statements regarding IBM's plans, directions, and intent are subject to change or withdrawal without notice.
